2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Sine wave. A power inverter device that produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter.

3. Electricity pricing - Wikipedia

   en.wikipedia.org/wiki/Electricity_pricing

   Electricity price forecasting (EPF) is a branch of energy forecasting which focuses on using mathematical, statistical and machine learning models to predict electricity prices in the future. Over the last 30 years electricity price forecasts have become a fundamental input to energy companies’ decision-making mechanisms at the corporate ...

   The M175 was packaged in a relatively large cast aluminum box. Wiring was passed through the case using compression fittings and the inverters connected to each other using a twist-lock connection. The product saw modest sales. Sales picked up with the second generation M190, [21] released in 2009. The M190 had a slightly higher power rating of ...

8. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The ...

9. Harmonics (electrical power) - Wikipedia

   en.wikipedia.org/wiki/Harmonics_(electrical_power)

   Because this is a deviation from a pure sine wave, the deviation is in the form of a periodic function, and by definition, the voltage distortion contains harmonics. When a sinusoidal voltage is applied to a linear time-invariant load, such as a heating element, the current through it is also sinusoidal. In non-linear and/or time-variant loads ...
